The LQH31CN4R7M03L: Murata has flagged this part as Last Buy. That means the production window is closing — if this inductor is on your BOM, the time to secure lifetime buy quantities or identify a drop-in replacement is now.
4.7 µH, 340 mA — the fit check
This is a 4.7 µH unshielded wirewound drum core inductor in a 1206 package. The 340 mA current rating and 845 mOhm max DCR set the DC loss budget — at full rated current, the I²R loss is about 98 mW, which the 1206 body dissipates without issue in still air up to 85°C ambient. The self-resonant frequency is 31 MHz, so it behaves as an inductor well below that — useful for DC-DC converter output filtering or power rail smoothing where the switching frequency stays under ~3 MHz to keep a healthy margin.
Board fit — 1206 footprint, unshielded
No shielding can means the magnetic field radiates — keep sensitive traces or other inductors a few body widths away to avoid coupling. Ferrite core material, ±20% tolerance. The 1 MHz test frequency for the inductance value is typical for power-grade ferrite inductors.
